To all whom it may concern:

Be it known that I, OnsoN P. SrANrrELo, a citizen of the United States; residing at Baxter Springs, in the county of Cherokee and State of Kansas, have invented certain new and useful Improvements in ChatDraw- 0's, of which the followingis a specification. I

This invention relates to chats separators of the class ordinarily used inconjunction with the commonly known type of jiggers having series of compartments provided with vertically oscillating plungers forforcing water up through grates or screens.

The invention consists in providing an auxiliary compartment in conjunction with the ore discharge box of a separator in order that the chats layers may be drawn ofi from between the waste and ore layersit being understoodthat the elfect of the separator is to classify or segregate the products dumped in the ore discharge box into distinct layers-the heaviest products generally the ore. A. further. embodiment of being the lowest. the devlce effects an efliclent and continuous scavenging of the chat separator by water,

a conduit beingprovided withcoimections with a water main or service pipe.

Other objects of the invention are to coir struct a chat separator which may be applied to a jigger or separator and when desired dismounted therefrom in a very short time and without any great labor or exertion; and also to provide a device which may be very quickly and easily manufactured at very small initial cost.

The above and additional objects are accomplished by such means as are illustrated in preferred embodiments in the accompanying drawings described in the following specification and then more particularly pointed out in the claims which are appended hereto.

In the drawings wherein is illustrated the preferred form of the invention:

Figure 1 is a transverse sectional view of an ore separator employing the present invention.

Fig. 2 is a detail perspective View of the invention disassembled to illustrate clearly the several parts included in this construction.

In describing my invention in detail reference will I be had to the accompanying drawings wherein like characters designate i like or corresponding inclined cover .Specification of Letters Patent. I i Patented N L'Q; 1920 Application filed October 21, 1919. l 3

Serial m m parts throughout the several views, and in which;

designates generally one of a series of ore separator compartments having the usual oscillating plunger B and ore" CllS' charge, box C within which is carried the chats separator designated in its entirety by D. A grating .or screen E supports the ore and permitsthe entrance of water which is forced up throughthe ore by action of the plunger B with suiiicient yelocity' to cause the various products to separateinto layers; three of which I have indicated as. ore, chats and waste. As this form of jigger" or ore separator is of a well known type I have merely shown-it here forthe purposes of illustration. a w 4 The chats separator per se (for a detail view of which see Fig.2) comprises a body portion 1 preferably 0 cast iron having an interior cavity or chamber Qthe bottom 3 of which is inclined downwardly from one end to the other with sufiicient pitch or fall to insure rapid flow of water and from throughan outlet opening 4: in the end wall of" the body portion communicating with the chamber 2 and having its lower edge flush with theibottom Thelower portion of the interionsi denwall of the body portion 1 is beveled or inclined downwardly adjacent the opening 4: and a plurality of spaced apart alined screw threaded openings 5 are formed therein extending longitudinally thereof adjacent the upper edgeof the body portion, for the reception of the screw threaded terminals of a plurality of street Us or elbows 6 adapted to extend within the chats layer to draw off the chats therefrom. An 7 having a plurality of bores 8 associated with other bores 9 in the body portion and for registration therewith to receive suitable securing means such as bolts chats there.

- engagement over the beveled edge of the ore In operation the chat box constructed asabove is placed on the interior of the ore discharge box C so that the street Us or el-- bows 6 extend within the chat bed, whereupon chats carried by the water issuing from the conduit 13; If found desirable, a suitable receptacle may be placed below the opening 4 to'receive the'chats upon their egress from the chats separator.

Attention is directed to the fact that the chat separator is held in place by its own weight, the inclined outstanding portion of the cover securely holding it in place through however suitable auxiliary securing means may be providedin the form of bolts (not shown) if found desirable.

Obviously structural changes of a slight naturewill be necessitated when this invention is reduced to practice and consequently I desire it to be understood that such changes may be made in the QIllllOfllIIlBl'lt herein illustrated and described as fall withseparator,

' in the scope of the appended claims.

What I claim is:

1. An attachment for ore-separators of the type indicated'including a cast-iron body portionhaving a chamber formed therein, the bottom wall of the chamber inclined downwardly from one end to" the other thereof, an outlet opening; in the body portion communicatingw-ith the chamber, screw threaded openings in p v y g 7 the body portion to engage upon one will be drawn off through the Us into the chamber 2 .wherefrom they will be,

the'body portion ador other ore-separator products to the chamher, a cover for the chamber, such cover being of approximately the same length vas the body portion but of a greater breadth and inclined downwardly with respect to y edge of the ore-separator to hold the attachment thereupon, and means communicating with the chamber through the cover for carrying the chats outwardly therefrom througlr the outlet opening. V p

2. An attachment for ore-separators of the type indicated including a body portion, having a chamber formedtherein, an outlet opening in the body portion communicating with the chamber, the bottom wall of the chamber inclined downwardly from one end to the outlet opening, a plurality of spaced apart longitudinally alined pipe elbows communicating with the chamber, a cover for the body portion inclined laterally with respect thereto, an outstanding portion of the cover disposed upon an adjacent wall of the separator to hold the attachment thereupon, a water inlet pipe extending through the cover and communicating with the chamber for, carrying the chats or ore products" outwardly therefrom through the outlet opening, and packing. between the cover and the body portion for preventing leakage of the, contents of the chamber out- .oRsoN P.
